The point of the tournament is to achieve the highest score overall. The rankings of members are decided by scores and advancement. The members who do not participate are automatically sorted in the lowest ranks by lottery. The highest score will become the highest ranked member for the tournament. If there are 32 participating, all members will be ranked or sorted regardless of their participation in the games.
